REMOVABLE RIM F01? VEHICLE-WHEELS.

To all wiwm it may comm: Be it known that I, CARROLL D. GALVIN', a citizen of the United- States, residing at Merchantville, county of Camden, State of New Jersey, have invented a new and useful Removable Him for Vehicle-Wheels, which the following is a specification.

My invention consists of a novel construction of removable rim carrying an outer treadwliich is adapted "to be readily disengaged from or secured to "the ordinary rim or felly of an automobile or other vehicle wheel, withbut necessitating the removal of the wheel, provision being made for s'uitabl Y protecting'the pneumatic tube employed roin puncture, heat and the like, the wear being taken up, upon an outer preferably solid tread of suitable resilient or other material, means. being provided for transference of motive power, lessening shocks in starting or stopping, reducing the oscillating effect of motion, when used for propelling purposes, reducing vibration caused by unevenness of roads, absorbing or diminisliing shock caused by the tire running over rough or uneven surfaces, thereby increasing the durability of the vehicle and mechanism carried thereby, provision being further made for thfe'cushioning of rebound shock and for greatly increased weightcarrying capacity.

To the above ends my invention consists in providing a novel construction of pneumatlc tube having the inner portion composed of 2. preferably continuous tube of material of novel contour in; cross section, *said material having suitably vulcanized or otherwise secured thereto,an outer casing,

having its inner and outer terminals suit-v ably secured in fixed position within rigid incasing plates or walls, which are securely held in assembled position by transverse fastening devices. I

It further consists of a novel combination of an outer preferably solid tread held in position with respect to the outer termi-' 113115 of the pneumatic device, by common fastening means, in combination with an outer felly having annularly recessed sides overhung by a'central member substantially 'T-shaped, in cross section, whereby I am enabled by the compression bf a troughit shaped-tube into said irecesses to form a Specification of Letters Patent; Patented Mar. 12,1912. Application filed December 6, 1911. Serial in. 664,139.

transverse leverage against the compressed air of the inflated side segments of the pneumatic tube'to resist side thrust from all directions.

It further consists ofa novel construction of a removable rim adapted to be readily fitted upon a wheel body or rim of the usual construction and to be held in position by outwardly flaring side flanges, which latter partially encompass the pneumatic tube, the outer terminals of the latter, beingisecured between the outer T-shaped folly and its restraining side flanges, which latter also serve to retain in assembled position the outer tread, which may besolid or hollow. It further consists in providing the inner and outer terminals of the pneumatic tube at noncompressible cores, which latter are re ceived and interlocked in wcdgeshape'd pockets in both the removable rim and the exterior felly, whereby when the parts are assembled a positive drive is given through these members for power to the outer tread.

'It further'consists in the combination of a removable rim having an exterior, concave surface juxtaposed to a similar con: centric, curved portion of the outer felly, whereby in case of the deflation of the pneumatic tube from any cause, the outer felly forms a riding member for the removable rim, without necessitating stoppage or cessation of the rotary motion of the wheel and enabling the same to be used to its destination.

It further consistsof other novel features of construction, all as will be hereinafter fully set forth.

For the purpose of illustrating my invention, I have shown in the accompanying drawings one form thereof which is at present preferred by me, since the same has been found in' practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my inventhe transmission of tion is not limited to the'precise arrangeresents, on a reduced scale, a sectional view of a wheel, having my invention applied thereto. Fig. 3 represents, on a reduced scale, a cross section of my novel pneumatic tube in detached position, showing particu larly the driving'flangcs thereof. Fig. 4 represents a side elevation of a vehicle wheel having my invention applied thereto. Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings, 1 designatesan outer tread member the same being preferably solid and of rubber or other resilient material, which is vulcanizedor otherwise secured upon a hard rubber base 2, my preferred construction being indicated in Fig. 1, wherein l have shown said hard rubber base 2 as dove-tailed into serrated apertures 3 in the wheel base or tire 4, which is cushioned by hard or vulcanized rubber, whereby a homogenous solid tire isproduced, the above parts being of the usual construction.

5 designates my novel construction of outer telly or anchor rim, which may be made of wood, fibre, tubing or other'material, whose exterior perimeter fits snugly upon the metal wheel base or tire 4, and is provided withthe beveled or outwardly converging walls,6, which are abruptly recessed or annularly concaved on the opposite sides as indicated at 7, said walls being extended outwardly, as indicated at 8, and thence reversely curved, as indicated at 9, the inner annular portion of said outer felly 5, being provided with a gradually curved surface 10, which is, by preference formed by the insertion of a separate filler or stittening member 11, whose contour will be understood .trcrn'Fig. 1, said member being secured in position by suitable fastening devices 12.

l3 designates a removable rim havin the outer concave wall H, which is curve onsubstantially the same radius as the curved surface 10 of the outer felly. l5 designates an inner metal tire suitably secured to the wheel felly, bod or rim 16, which latter is standard or o usual construction. The removable rim 13 is provided on its opposite sides with the beveled or inwardly converging walls 17, whereby the wedgeshaped recesses 18 are formed between said walls 17 and the outer annular flanges of the retaining side plates 19, whose inner portions 20 are secured to the wheel rim 16, while their outer portions .21 are fia-rcd out wardly and project for a considerable distance beyond said removable rim 13. 22 designates the pneumatic tube, whose con struction will be apparent from the enlarged view Fig. 1, said tube consisting of the inner portion 23, which is shaped so as to conform to the curved. surfaces 7, 8, 9, l0

and 1% already described, so that when indated, the outer contour of said tube col forms to the contour of the inner walls c the flaring portions 21 of the side retainin plates 19.

In practice, I secure to the outer sid portions of the pneumatic tube 22, by vol canizing or otherwise, the annular merr hers 24, whose inner terminals-.25, are prc vided with the wedgcrshaped cores 26 0 suitable non-compressible material, thereb distending the inner terminals oi": said mem bers 24, which latter are located and inter locked in the annular wedge-shaped pools ets 18, so that when the transverse bolts 2 are tightened, the outer plates l9-are assern bled in substantially the position seen i1 Fi .1 with respect. to the removable rim 13 an the inner terminals 26, will be firml: interlocked in the annular wedgeshapu pockets 18 against all displacement. 21 designates other-transverse fastening de vices, which extend through the portions 2 of the side plates 19, whereby the latter an ftightly secured in engagement with thi es of the wheel rim or body 16.

29 designates a plurality of plates 0: metal or other suitable material, which art secured to the sides of the outer tread mem her 1 by means of transverse fastening de vices 30, itbeing apparent that a-wedge shaped pocket 31 is formed between tlu inner walls of said plates 29 and the juxtaposed beveled walls 6, of the outer telly 5 in which pockets are seated the outer terminals 32 01' the annular members 24, said terminals being provided with annular wedgeshaped cores 33, whereby said outer terminals are given a' wedge-shaped contour, so that the same can be readily interlocked in said wedge-shaped pockets 31 upon the tightening of the bolts 30, whereby power is transmitted directly from the rim to the outer tread member 1, through the medium of the outer casings 24, and tube 23, which is vulcanized or otherwise secured thereto.

34 designates an air tube communicating with the interior of the tube 22, wherebythe latter can be inflated according to requirements.

In Fig. 2 I have shown the application of my invention to the ordinary wooden wheel now commonly employed on automobiles and similar vehicles, 35 designating the hub of said wheel and 36 the wooden spokes thereof. I desire to call special attention to the fact thatmy invention, in its broad aspect, comprises the removable rim 13, the side plates 19, the telly 5, the pneumatic tube 22 constructed as shown the outer tread 1 and the connecting devices common to said outer tread, the pneumatic tube and the telly 5, provision being thus made for enabling my invention to be readily and quickly applied to the wooden or other We hicle wheels standard size now commonly employed by merely manipulating the bolts 28.

In my novel constructionit is'- only necessary to inflate the inner pneumatic tube to about twenty pounds .pressurewhich is'a very great advantage over the present typeof. exterior pneumatic tubes, which ordi-- nariiy require an'air pressure of. froni'eightyi to ninety pounds. It will further belapparent that in my novel construction the pneumatic tube is entirely removed from contact with the earth orth'e'road whereby'there is .no liability whatever fOIiLhB tube to become des'cribed by-the employmentof'the concen trio'ourvature of the removable rim and fell? 5, results: in the formation of a restraining wall which cushions all rebound of the down thrust of the load, and forms a circular internal shock absorbing] cushion Xithin the wheel, where all shocks from c cry direction are cushioned at substantially right angles 'to any point of occurrence by the opposite segmentof the tube and the restraining wall of the rim.

The pneumatic tube 22 may be formed of la'yers of fabric and rubber and the outer w portions 2 L having the terminals 32 and 25 may be constructed of sheet rubber and fabric vulcanized or otherwise secured together thereby forming flexible outer reinforcing walls for the inner tube 22, said inner and outer terminals 25 and 32, when assembled in the position seen in Fig. 1, in their wedge-shaped pockets and compressed by their respective draw-bolts, form not only a casing for the inner tube but in addition serve the function of driving belts for the transmission of motive power to the outer perimeter or tread 1 of the wheel. By my novel construction of pneumatic tube 22, which as seen in Fig. 3 is preferably of substantially U or horse-shoe shape having its curved portions ST-deflQcted toward each other; it. will be seen that the same coacts with the overhanging flanges 9 of thorim, the; telly thereby cushioning and resisting all side thrust and any deflation from the norma1. contour of the inflated tube,

"while in the case of deflation of the inner tube 22, by reason of the concentric juxtaposed curvatures at the points 10 and 14,

and 14 can ride upon each other without detriment-to the Wheel.

It will be apparent that by my novel construction and location of the pneumatic tube 22 and its adjuncts, noise caused .by the contact of the tire with the road will be ab- -vsorbedand, in addition, vibration and shock will be reduced to a minimum thereby giv- -'.ing ease and comfort to the'occupants of the lgelhicle and in addition increasing its dura- 1 ity, Having thus described my. invention, what I claim-as new and desire to secure by Letters Patent, is
